(57) Disclosed is a thermoplastic resin composition having a matt appearance comprising:

(A) 80-5 parts by weight of graft copolymer obtained by grafting 40-95 parts by weight of diene rubber with 60-5 parts by weight of vinyl compounds consisting of 0.1-40 weight % of at least one glycidyl ester of an a-and β-unsaturated acid as an essential component, 10-40 weight % of a least one vinyl cyanide compound, 60-90 weight % of a least one aromatic vinyl compound and 0-30 weight % of other copolymerizable vinyl compounds, and

(B) 20-95 parts by weight of a copolymer obtained through reaction of 10-40 weight % of at least one vinyl cyanide compound, 60-90 weight % of at least one aromatic vinyl compound, and 0-30 weight % of other copolymerizable vinyl compounds, the intrinsic viscosity of the resin composition in terms of its components soluble in methyl ethyl ketone being 0.25-1.5 di/g (N,N'-dimethyl formamide solution, 30 °C).
